Most emails are of little value. We often remember the extraordinary, like the once-in-a-lifetime invitation, but not the ordinary - that possibly only three percent of emails are worth reading.

We often impose an unhealthy expectation on ourselves to respond to every email immediately.
Except for work assignments, this is unnecessary. Many people will applaud you for taking a break and find your decision inspiring.

We expect information to come to us, rather than proactively seeking it out. 

Our news email means we don't have to search it out. Our event invites mean we don't have to look into what's happening. While it is convenient, we are conditioned to become lazier.

There are so many things funneling back to email.

Without email, it can be difficult to check a doctor's appointment, RSVP to party invites, or access your bill history. Email can be a nightmare if you're trying to create boundaries.

Spending a month away from email can help you question your default distractions.
Without email, you have to find other stuff to do while riding on the subway or waiting in line. Then you may realize that self-importance and the sense of urgency are not important.
